Marked.js is a high-performance JavaScript library designed specifically for parsing and compiling Markdown into HTML. Its core philosophy is speed, making it an excellent choice for applications where rendering Markdown content quickly is a necessity. Whether you're building a blog, a documentation site, a forum, or even a command-line interface tool, Marked.js offers a robust and lightweight solution.
Key Features That Set Marked.js Apart:
- Speed and Efficiency: Built with performance in mind, Marked.js minimizes caching and blocking operations, ensuring rapid parsing even with large Markdown files.

- Cross-Platform Functionality: Marked.js isn't limited to a single environment. It works seamlessly in browsers, on Node.js servers, and can even be utilized via a command-line interface (CLI).
- Lightweight Impact: Despite its comprehensive feature set, the library maintains a small footprint, making it easy to integrate without adding significant bloat to your projects.
Getting Started with Marked.js:
Integrating Marked.js into your workflow is straightforward. You can install it globally for CLI usage or as a project dependency via npm.
For CLI Usage:
npm install -g marked
For Browser or Node.js Projects:
npm install marked
Usage Examples:
The library provides clear examples for both CLI and in-browser use. For instance, in the browser, you can render Markdown directly into an HTML element:
<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
<title>Marked in the browser</title>
</head>
<body>
<div id="content"></div>
<script src="https://cdn.jsdelivr.net/npm/marked/lib/marked.umd.js"></script>
<script>
document.getElementById('content').innerHTML =
marked.parse('# Marked in the browser\n\nRendered by **marked**.');
</script>
</body>
</html>
Important Security Note: Marked.js itself does not sanitize the output HTML. For security against XSS attacks, it is highly recommended to pair Marked.js with a sanitization library like DOMPurify.
